Peace of mind is a Mental State of Calmness or tranquility, a freedom from worry and anxiety. When the bills are piling up, the kids acting up, the spouse not on the same page as you are, life can seem so overwhelming.
Job loss, stress, death of a love one, and even mental illnesses. If you dwell on what is seen long enough, you can definitely lose faith in God or even life itself. When problems arise and they will come to us all, run to the rock that is higher that we are. That rock is Jesus. For He is a very present help in times of trouble. Psalm 46:1
Jesus is a problem solver, a heart fixer, a mind regulator. Let the peace of the Lord be with you wherever you go. Don't leave home without the Prince of Peace. Read the word of God. Pray. Seek Gods face and His leading and direction of your life; just don't lose hope or give up on what God has promised you. He is always there waiting on you to talk to Him, call on Him.
Jeremiah 33:3 Call on me and I will answer you and show you great and mighty things which thou know not of. True peace will flow like a river in your life when you take your eyes off of the situation and put it on the Lord Jesus Christ the True Prince of Peace.
